Hello !   Is Petti there ?   I'm sorry , I'm afraid you've dialed the wrong number . There is no Petti here .   Wrong number ? Are you sure ? I called yesterday and she was there .   I'm sure you have the wrong number . This one has been my number for more than 20 years .   That's impossible . I remember the number clearly . Isn't this 763-4565 ?   No , It isn't . It's 736-4565 . It seems you've misdialed .   Really ? I ' m so sorry I bothered you . I ' ll try again .   That's all right . This sort of thing happens all the time to everyone .   Yeah . I guess it does . Sorry again for bothering you .   No worries .
